As shown in Figure 1 and Figure 2, Via bile duct explosion respectively provided by the embodiment of the utility model takes at stone auxiliary device
In the schematic diagram of unaerated state and inflated condition, as seen from Figure 1, Figure 2, the Via bile duct explosion of the utility model embodiment is taken
Stone auxiliary device includes: the support tube 2 for being placed in cystic duct 5；The inflatable bladders being coated in the middle part of 2 outer wall of support tube
3；The gas injection component for gas injection into it connecting with inflatable bladders 3, has the gas tube 1 being connected to inflatable bladders 3；
The attraction component of calculus for being sucked out in choledochus, having may pass through the suction tube 7 that support tube 2 is extend into choledochus 6；Its
In, 1 part of gas tube is moved under water in support tube 2, and one end penetrate the side wall of support tube 2 after be connected with inflatable bladders 3.
Wherein, gas injection component include gas tube 1 and the syringe being detachably connected with the inflating port of gas tube 1 (in figure not
It shows).The setting of 1 other end of gas tube can automatic rebounding to block the closeouts of inflating port, it is preferred that closeouts are rubber stopper
Or elastic component (not shown), elastic component can be spring.
, can be by rubber stopper plug at the inflating port of gas tube 1 when closeouts use rubber stopper, and rubber stopper is using doctor
With rubber stopper, when being inflated using syringe into gas tube 1, the syringe needle of syringe is pricked into rubber stopper, and after the completion of inflating, it pulls out
Syringe needle out, due to the elasticity of rubber stopper, the pin hole that syringe needle is pricked out is closed, to prevent outside the gas in gas tube 1 and air bag
It lets out.
When closeouts use elastic component, bulb 4 is set at the close inflating port of gas tube 1, elastic component is disposed
In bulb 4, when design, the outer diameter of elastic component should be made to be greater than the diameter of 1 inflating port of gas tube.Connect in syringe and inflating port
Connect and into air bag 3 after gas injection, loosen the piston handle of syringe, then elastic component automatic rebounding and block bulb 4 and inflation
1 part of gas tube between mouthful, to prevent the gas leak in air bag.
Wherein, the flexible plastic tube of long 15cm or so can be used in gas tube 1, this plastic tube moves under water in 2 tube wall of support tube,
It penetrates 2 outer wall of support tube after to 3 midpoint of air bag to communicate with air bag 3, air bag 3 is nested on the outer wall at 2 middle part of support tube, preferably
, using the thin good annular air-pocket of elastic force of wall, when unaerated, can be covered on 2 outer wall of support tube and will not be from support air bag 3
2 outer wall of pipe falls off.After support tube 2 is placed in suitable position by cystic duct 5 (as shown in Figure 4), pass through gas tube tail end
Inflating port is nested with the expansion expansion of air bag 3 on 2 outer wall of support tube in spherical arc shape to gas at this time, when to gas to it is a certain amount of after, gas
3 outer surface of capsule can be close to bile duct wall, on the one hand with fixed support tube 2, can on the other hand make the choledochus 6 of 2 distal end of support tube with
Ductuli hepaticus communis and stones in intrahepatic bile duct isolation (as shown in Figure 5).
Wherein, support tube 2 uses the hard hollow plastic pipe of slightly radian, and inner diameter size can take stone biliary tract by conventional
Mirror, generally between 5.5mm-6.5mm, it is preferred that 2 internal diameter of support tube is 6mm,.When design, the side wall of support tube 2 opens up logical
Hole is connected so that gas tube 1 may pass through through-hole with air bag 3.
Wherein, the attraction component of the present embodiment includes suction tube 7 and the aspirator that is detachably connected with suction tube 7.Attract
The tough plastic tube of matter can be used in pipe 7, and plasticity is good, and the outer diameter of suction tube 7 is less than the internal diameter of support tube 2, so as to wear
It is located in support tube 2, one end of suction tube 7 may connect to conventional use of aspirator, and another distal end can be placed in by support tube 2
(not shown) in choledochus 6.Wherein, aspirator is detachably connected (as shown in Figure 3) by connector 8 and suction tube 7, e.g.,
Connector 8 modes such as can be used grafting with suction tube 7 or be spirally connected and links together.Preferably, aspirator can use vacuum suction
Device, so that the microlith after the explosion in choledochus 6 be sucked out by negative pressure.Alternatively, can be used can be into suction tube for aspirator
The device of the prior art of gas injection or water filling is gone out with will pass through suction tube for microlith.
When using the auxiliary device of the present embodiment carrying out that stone is taken to operate, support tube 2 is placed in suitable position by cystic duct 5
It postpones, is inflated to gas tube 1 so that the expansion of air bag 3, support tube 3 is fixed in choledochus 6, choledochoscope passes through by syringe
Support tube 2 enters 6 blasting broken stone of choledochus, until on the one hand passing through choledochoscope lithotomy net after calculus diameter is less than 2 internal diameter of support tube
Take out compared with maximum size, on the other hand via support tube 2 be placed in suction tube 7, by aspirator be sucked out microlith, biliary tract spectroscopy without
It is deflated by syringe to air bag 3 after calculus, so that support tube 2 be taken out out of cystic duct 5.
After the support tube 2 of the present embodiment is fixed on choledochus 6 by air bag 3, the choledochus 6 of 2 distal end of support tube can be isolated
With ductuli hepaticus communis, stones in intrahepatic bile duct, so that the calculus after blasting broken stone will not be floated into ductuli hepaticus communis and stones in intrahepatic bile duct, and choledochoscope can pass through
2 Via bile duct 5 of support tube takes out maximum size, and suction tube may pass through support tube 2 and be sucked out or go out microlith.
Compared with prior art, the Via bile duct explosion of the utility model embodiment takes stone auxiliary device to have following excellent
Point:
The Via bile duct explosion of the present embodiment takes stone auxiliary device, and gas tube, suction tube are through in support tube simultaneously, structure
Simply, easy to use, convenient for taking out through the cystic duct in small space compared with maximum size and multiple microlith, and can be isolated after air bag expansion
Choledochus and ductuli hepaticus communis, stones in intrahepatic bile duct, avoid calculus from floating through choledochus into ductuli hepaticus communis or stones in intrahepatic bile duct, avoid taking stone difficult or nothing
Method takes out calculus, and the placement T caused by calculus can not take out or take stone inaccurate is also avoided to manage due to give patient increased pain, benefit
In patient's early recovery.
Although being explained in detail above to the utility model embodiment, the utility model embodiment is without being limited thereto, this
Those skilled in the art can modify according to the principle of the utility model embodiment, therefore, all practical new according to this
